Function Improvements
for Unit Version 2.0
xxvi
Jogging
Previous versions
The JOG feed direction is set or reversed
as follows:
• Use the JOG/STEP Direction Bit to
specify the feed direction.
• Turn ON the JOG Bit.
• To reverse the feed direction, turn OFF
the JOG Bit.
• After the axis is stopped, reverse the
JOG/STEP Direction Bit.
• Turn ON the JOG Bit. The feed direction
will be reversed.
Communications Levels
Previous versions
The MC Unit supported communications
on up to three levels.
Communications Cycle and Unit Cycle
Previous versions
The MC Unit communications cycle and
unit cycle times are as follows:
Communications cycle: 1 ms, 2 ms, 4 ms
Unit cycle: 1 ms, 2 ms, 4 ms, 8 ms
LATCH Command Processing Time
Previous versions
The time from when the LATCH com-
mand is executed until the external latch
signal is detected is as follows:
• When latch signals are received at any
position: 105 to 232 ms
• When only latch signals in a specified
position range are received: 105 to
232 ms
Current version (Unit Ver. 2.0)
As shown below, a setting for reverse
operation has been added.
• Use the JOG/STEP Direction Bit to spec-
ify the feed direction.
• Turn ON the JOG Bit.
• The feed direction is reversed by revers-
ing the JOG/STEP Direction Bit even
while the JOG Bit still ON.
Use the following parameter to switch the
previous function and the new one.
• Parameter number: P00004
• Bit: 05 (previously reserved)
0: Initial value. Same as previous func-
tion.
1: Selects new function.
Current version (Unit Ver. 2.0 or later)
The MC Unit supports communications on
up to eight levels, according to the eight
levels supported by the CPU Unit. The
CPU Unit supports eight levels with unit
version 2.0 or later.
Current version (Unit Ver. 2.0 or later)
• Supporting a communications cycle of
3 ms enable more precise performance.
Communications cycle: 1 ms, 2 ms,
3 ms, 4 ms
Unit cycle: 1 ms, 2 ms, 3 ms, 4 ms, 6 ms,
8 ms
• Use the following parameter to switch the
previous function and the new one.
Parameter number: P00004
Bit: 03 (previously reserved)
0: Initial value. Same as previous func-
tion.
1: Enables use of 3 ms.
Current version (Unit Ver. 2.0 or later)
As shown below, performance is improved
in cases where latch signals are received
at any position.
• When latch signals are received at any
position: 3 to 24 ms
• When only latch signals in a specified
position range are received: 105 to
232 ms
